The period of this binary seems to be about 750 years.
Turning next towards the south-west we see the second-magnitude star [epsilon] Pegasi, some 40 deg.

above the horizon.

This star is a wide but not easy double, the secondary being only of the ninth magnitude; its colour is lilac, that of the primary being yellow.
Towards the right of [epsilon] Pegasi and lower down are seen the three fourth-magnitude stars which mark the constellation Equuleus.

Of these the lowest is [alpha], to the right of which lies [epsilon] Equulei, a fifth-magnitude star, really triple, but seen as a double star with ordinary telescopes (Plate 5).

The distance between the components is nearly 11", their colours white and blue, their magnitudes 5-1/2 and 7-1/2.
